1. 设置新库为非归档模式，关闭flashback
节点2执行：
srvctlstop database -d prdweb
sqlplus/ as sysdba;
startupmount
alterdatabase flashback off;
alterdatabase noarchivelog;
alterdatabase open;
exit;
srvctlstart instance -d prdweb -i prdweb1
2. 查看旧库的tnsnames.ora，将旧库的tnsname.ora配置到新数据库
3. toad查看旧库的db_profiles，所有的profiles 导入到新库
4. 查看旧库的role，如果有用户自建的role，需要先在新库建立
5. 列出要导出的用户，查看要导出数据大小，对象数
select k.owner, k.MB, j.n
from(select t.owner,sum(t.bytes)/1024/1024as MB
from dba_segments t
where t.owner in('AUDITOR',
'CERT',
'DATAINFO',
'DBCENTER',
'DBCENTERJJ',
'DBCENTERJJ2',
'DBCENTER_TEST',
'GAZX',
'GGZD',
'HKKH',
'HQ2010',
'HT3G',
'HTDBTRANSFER',
'HTJKMON',
'HTSC',
'HTSQL',
'HTZQ',
'JS',
'MNCG2010',
'MON_GW',
'TO',
'VIRTUALTRADE',
'WEBBRANCH',
'WFG_ADMIN',
'ZGZWZ',
'ZHANGLE',
'ZHANGLE_CERT')
groupby t.owner) k,
(select t.owner,count(*)as n
from dba_objects t
where t.owner in('AUDITOR',
'CERT',
'DATAINFO',
'DBCENTER',
'DBCENTERJJ',
'DBCENTERJJ2',
'DBCENTER_TEST',
'GAZX',
'GGZD',
'HKKH',
'HQ2010',
'HT3G',
'HTDBTRANSFER',
'HTJKMON',
'HTSC',
'HTSQL',
'HTZQ',
'JS',
'MNCG2010',
'MON_GW',
'TO',
'VIRTUALTRADE',
'WEBBRANCH',
'WFG_ADMIN',
'ZGZWZ',
'ZHANGLE',
'ZHANGLE_CERT')
groupby t.owner) j where k.owner=j.owner orderby k.MB desc
select t.owner,t.object_name,t.object_type from dba_objects t where t.status='INVALID'
6. 导出数据
timeexpdp \'/ as sysdba\' directory=dpdir Exclude=Statistics Compression=metadata_onlydumpfile=prdweb_struc.dmp logfile=prdweb_struc.log full=y content=metadata_only
datafile=prdweb_`date'+%Y%m%d'`_%U.dmp
logfile=prdweb_`date'+%Y%m%d'`.log
timeexpdp \'/ as sysdba\' directory=dpdir Exclude=Statistics dumpfile=$datafilelogfile=$logfile filesize=20G parallel=10 full=y version=10.2.0.4
7. 创建数据库泵路径
createdirectory dpdir as ' /backup/dpdir';
8. 导入db_links
timeimpdp \'/ as sysdba\' directory=dpdir INCLUDE=DB_LINK dumpfile=prdweb_struc.dmplogfile=prdweb_imp_dblink.log
9. toad导出表空间脚本，到新库重建
10. 数据导入到目标库
directory=dpdir
table_exists_action=truncate
data_options=skip_constraint_errors
skip_unusable_indexes=y
parallel=10
schemas=AUDITOR

version=11.2.0.4
timeimpdp \'/ as sysdba\' parfile=prdweb.par logfile=prdweb_imp_`date'+%Y%m%d'`.log
11. toad导出用户创建脚本，将用户授权重新执行一遍
sqlplus/ as sysdba;
@grant.sql
12. 编译失效对象
remrecompinvalid.sql
remrecompile invalid objects
sethead off
setfeedback off
setlinesize 200
setpagesize 0
spoolrecompinvalidsub.sql
selectdistinct 'execute dbms_utility.compile_schema('''||OWNER||''',FALSE);' fromDBA_OBJECTS where status='INVALID';
spooloff
setecho on
setfeedback on
settiming on
@recompinvalidsub.sql
13. 对比之前步骤得到的原库的失效对象和导入以后的失效对象，手动创建。
CREATEINDEX "CDC_INFO"."TEST_T_PACKAGE_INFO2_IDX1" ON"CSP_INFOS"."TEST_T_PACKAGE_INFO2" ("UPDATEID")TABLESPACE "CDC_INFO";
14. 手动收集所有用户的统计信息
EXECDBMS_STATS.GATHER_SCHEMA_STATS (OWNNAME=>'AUDITOR' ,CASCADE=>TRUE,DEGREE=>24 );
EXECDBMS_STATS.GATHER_SCHEMA_STATS (OWNNAME=>'CERT' ,CASCADE=>TRUE,DEGREE=>24 );

EXECDBMS_STATS.GATHER_SCHEMA_STATS (OWNNAME=>'ZHANGLE_CERT' ,CASCADE=>TRUE,DEGREE=>24 );
15. 设置辛苦为归档模式，flashback打开
srvctlstop database -d prdweb
sqlplus/ as sysdba;
startupmount
alterdatabase archivelog;
alterdatabase open;
alterdatabase flashback on;
exit;
srvctlstart instance -d prdweb -i prdweb1
